Description

Verfahren zur Entschwefelung von Gasen Zur Entschweflung von Gasen mittels geformter Masse hat man sich bisher zweier Türme bedient, von denen der eine auf Luft und der andere auf Gas arbeitete. Durch periodisches Umschalten wurde der eine Turm regeneriert, während in der 2#vischenzeit der andere Turm die Gasreinigung übernahm. Bei den mit hohen Geschwindigkeiten (etwa roo innifSek.) arbeitenden Gasreinigern gelingt es auch bei verhiiltnisiniißig geringen Schwefelgehalten nicht, die Regeneration rasch genug durchzuführen, wenn man nicht die oben benannte Betriebsweise mit den zwei Türmen anwandte.Process for the desulphurisation of gases For the desulphurisation of gases by means of molded mass, two towers have so far been used, one of which is the one worked on air and the other on gas. By periodically switching one tower regenerates, while the other tower cleans the gas during the second phase took over. In the case of the gas purifiers that work at high speeds (e.g. roo innifSek.) If the sulfur content is relatively low, the regeneration does not succeed to be carried out quickly enough if one does not use the above-mentioned operating mode with the applied two towers.

Vorliegende Erfindung zeigt nun den Weg, wie man an Stelle der beiden Türme einen einzigen Turin anwenden kann uncl dadurch die Baukosten und Betriebsweise erheblich vereinfachen kann. Die Anwendung des vorgeschlagenen Verfahrens betrifft vor allein Gase mit inaßigein Schwefelgehalt, insbesondere Generator- und Wassergas.The present invention now shows the way how to replace the two Towers a single Turin can use and thereby the construction costs and operation can greatly simplify. The application of the proposed method concerns mainly gases with an inassive sulfur content, especially generator and water gas.

Gemäß der 1?rfindun" wird die am Gaseintritt liegende scli\vefelreiclie--Masse periodisch oder laufend ali"ezogen, an der Luft regeneriert und in der \fitte des Turnfes wieder zugegeben.According to the figure of the invention, the sensitive mass located at the gas inlet becomes Periodically or continuously pulled out, regenerated in the air and in the middle of the Turnfes admitted again.

Es ist zwar bekannt, lose --lasse bei Nochreinigern am Gaseintritt abzuziehen und nach erfolgter Wiederbelebung oben auf den Turm ani Gasaustritt aufzugeben. Diese Arbeitsweise bedingt jedoch, (laß schwefeihlltige Masse bis zum Reinigungsaustritt gelangt. Da schwefelhaltige -lasse nicht in der Lage ist, Schwefelwasserstoff im selben Maße zu binden wie sch-,vefelfreie Masse, so wird durch diese Störung des Gegenstroinpriii-ril)s ein empfindliches Nachlassen der GasreiiiigunCr bewirkt, Glas sich insbesondere bei den zur Anwendung- geförniter Reinigungsmasse benutzten Turmreinigern, die mit hohen Geschwindigkeiten arbeiten, bemerkbar macht. Die Arbeitsweise geniiiß der Erfindung beseitigt alle Nachteile, wie an Hand nachstehender Beschreibung und Zeichnung hervorgeht.It is known to leave it loose at the gas inlet when cleaning agents are still in use withdraw and after resuscitation give up on top of the tower ani gas outlet. However, this method of operation requires got. Since sulphurous -lasse is not able to absorb hydrogen sulphide in the To bind the same measure as the non-defective mass, this disturbance of the Counter flow control causes a sensitive decrease in gas flow, Glass is used in particular for the application of the granular cleaning compound Tower cleaners working at high speeds. The way of working The benefit of the invention eliminates all disadvantages, as described in the following and drawing emerges.

In den Entschweflungsturm tritt das Gas bei b ein, durchstreicht die 1-Tasseschicht a und tritt bei c aus. Der Türm wird bei Inbetriebnahme durch die Füllschleuse c init der geformten Gasreinigungsmasse gefüllt. Mit zunelinicnder Verschweflun- wird ein Teil der -Masse bei il abgezogen, an der Luft regeneriert und durch die Füllschleuse f in den Turm gegeben. Diese regenerierte -Masse rutscht durch das Füllrohr g während des periodischen Abziehens der -Masse iin Verlauf der dauernden Entschweflung in die Mitte des Turmes und mischt sich dort mit der aus der Füllscbletise t kommenden Frischmasse. je nach der Weite des Einbaues j kann (las Verhältnis von Frischinasse und regenerierter Masse den -\Terscliweflungsbedingungen entsprechend geändert werden- Bei Gasen mit hohem Schwefelwasserstoffgelialt nimmt inan das Rohr ä enger und erhöht dadurch den Anteil an Frischmasse. Bei Gasen mit niedrigem Schwefelwasserstoffaehalt nimmt man das Rohr ,weiter und vermindert dadurch den Anteil an Frischmasse. Das Gegenstromprinzip ist bei dieser Anordnung- voll gewahrt, und das zu reirnigende Gas strömt am Gasaustritt stets durch völlig schwefelfreie Frischmasse. Der Umlauf der schwefelhaltigen Mässe vom Ende bis zur 'litte des Entschweflungsturmes gewährt die schnelle Regeneration ohne Anwendung eines zweiten Turmes.The gas enters the desulphurisation tower at b and passes through the 1 cup layer a and exits at c. When the tower is put into operation, the Filling lock c filled with the formed gas cleaning mass. With zuelinicnder Part of the mass is drawn off at il and regenerated in the air and fed into the tower through the filling sluice f. This regenerated mass slips through the filling pipe g during the periodic removal of the mass i in the course of the permanent desulphurisation in the middle of the tower and mixes there with the the filling quantity t coming fresh mass. depending on the width of the installation j can (read the ratio of freshly immersed and regenerated Mass the - \ separation conditions be changed accordingly- For gases with high hydrogen sulfide gelialt increases in to the pipe a closer and thereby increases the proportion of fresh mass. For gases with If the hydrogen sulphide content is low, the tube is taken further and thus reduced the proportion of fresh matter. The countercurrent principle is full with this arrangement and the gas to be cleaned always flows through completely sulfur-free at the gas outlet Fresh mass. The circulation of the sulphurous measures from the end to the middle of the desulphurisation tower grants quick regeneration without using a second tower.

Sollte das zu entschwefelnde Gas im Verhältnis zum Schwefelwasserstoff zu wenig Sauerstoff enthalten, so setzt man dem Rohgas etwas Luft zu. Bei Generatorgas wird . die Geschwindigkeit -der Regeneration innerhalb des Turmes noch unterstützt durch die verhältnismäßig warmen Gase, welche in dem Turm eine Betriebstemperatur von etwa 30° zu halten gestatten.Should the gas to be desulphurized in relation to the hydrogen sulphide contain too little oxygen, some air is added to the raw gas. With generator gas will . the speed of regeneration within the tower is still supported by the relatively warm gases, which an operating temperature in the tower of about 30 °.

Das ist selbstverständlich auch für Anlagen mit Vorteil anwendbar, welche unter Druck entschwefeln.Of course, this can also be used to advantage for systems, which desulfurize under pressure.
